摘要：

The polarographic reduction of the 3'-halogen derivatives of N,N-dimethyl-4-aminoazobenzene was studied in mixed water-methanol medium and optimum conditions were found for the determination of these genotoxic substances by tast polarography in the concentration range 1.10(-4) to 2.10(-6) mol l-1, differential pulse polarography at a dropping mercury electrode in the range 1.10(-4) to 2.10(-7) mol l-1 and fast scan differential pulse voltammetry at a hanging mercury drop electrode in the range 1.10(-6) to 2.10(-8) mol l-1. The increase in the sensitivity resulting from adsorptive accumulation of the studied substances on the surface of a hanging mercury drop can be utilized in the determination using the latter method in the concentration range 1.10(-8) to 2.10(-9) mol l-1.
